Boss - Metal Gear Ray | The Main Campaign - walkthrough MGR: Revengeance Guide
Last update: 11 May 2016
Unfortunately, this is another rehashed idea. The fight with Ray is also no different than in the case of the one fought as Raiden. Which is why, describing it all over again makes no sense. Go to the chapter devoted to the game's bosses, in case of any problems.
After you have dealt with the boss, you need to find the collectibles, which are plenty here. The first one (a Fuel Cell) is in the South-Eastern part of the hangar - look for the plank suspended above the ground and get there with the double-jump.
Then, go to the Western part of the hangar and climb onto another plank above the ground. You will find a VRM computer there - for completing its mission, you will receive an Endurance Plus.
Another item (a Data Storage) is located directly above you, on the venting shaft (look at the above screenshot to learn how to get there; your position has been marked in blue). After you have collected everything, go towards the marker - to get to the gate, you will have to cut through the fence with the Blade Mode.
When opposite the gates, pan the camera upwards - you should notice another metal plank here. Jump onto it and over onto another one, until you reach a crate with Endurance Plus inside. Collect the item and go to the gate.
After a while (and a fight with two heavily-armored cyborgs) you should reach a familiar place - the Japanese garden. Once you cross the gate, look up. Jump onto the rooftop and onto the plank, where there is a crate with the collectible inside (Fuel Cell). Then, go for the palace which you have been recently climbing up.
Deal with all the enemies in your way and walk through the palace to the other side and turn left - you should be looking at a crate with Endurance Plus right now. Collect it and climb onto the top of the palace (use the double-jump for that, to avoid using lamps, which you have been recently jumping over).
You are up for a fight with several cyborgs here. After you have killed one of them, note the airborne slider. Shoot it down with the rocket launcher and it will drop another Endurance Plus. Kill out the rest of them, jump off the palace and go towards the marker, where you will fight cyborgs and Fenrirs.
After the fight, leave the building and turn left, after you reach the fork. At the end, you will find a VRM computer. The mission that you will have to complete the here is extremely difficult and you will have to fight several opponents (Mastiffs, Fenrirs, Raptors), to fight, eventually, the boss (GRAD). After you complete the this mission, you will not receive any upgrade so, if you are not bent on completing all of the VRs, you can ignore it.
Regardless of your decision, take the other branch in the fork, towards the marker. You are up for a fight with several Mastiffs, and a lot of cyborgs here. After you have dealt with all of them, look onto the wall opposite the elevators and note the fragment that stands out from the wall's shade. Use the Blade Mode to cut through that point and reach the hidden data Storage. Take the elevator ten and go up.
After you exit the elevator, pick up the box and the repair nanopaste from the brown crate. All of the door, apart from the one marked on your radar, are blocked at this moment, but you will be back in a moment. Eliminate the Gekko along your way and enter the server room. Clear the entire room, so you can move more freely here. After you are done, find a crate (Endurance Plus) hidden under the stairs.
Collect all of the upgrades and climb up the stairs. Soon, there will appear a green dot on the map (which marks a side mission) - you will fight two GRADS there but, you will not be rewarded for that so, you do not really need to go there. On one of the rods/columns you will find a Data Storage. Double-jump to get onto the rods. After you have collected the item, activate the console at the door. After a while, there will appear enemies in the server room - kill every last of them and collect the access cards that they dropped.
Now you can return to the room that the other green dot is pointing to (this location was inaccessible, at first). Inside, find a crate (Fuel Cell) and the last VRM computer next to it. Once you activate the mission, the view will change to the old-school platform style. Continue along your path, until you reach the Endurance Plus.
However, it is under stairs and you need to rack your brains a bit, before you will be able to obtain it. Keep going left, until you reach a place with a platform that moves vertically. Jump down on that platform and go left, until you reach the upgrade. Return now to the place where you jumped down onto that platform and jump up, to complete the VR mission.
Now, The last thing for you to do is go towards the marker, to meet the final boss of this mission pack.
